SparkFun Gimbal Motor 12V 467RPM (With or Without Encoder)

A compact 40mm brushless gimbal motor wound for smooth, high-torque control at low speed — the job of a camera gimbal axis, a pan-tilt head or a small robotic joint. It is rated 467RPM nominal at 12V and comes in two versions: bare, for open-loop brushless gimbal controllers, or fitted with an AS5048A magnetic encoder for closed-loop position control.

Key features

• 0.09N·m nominal and 0.15N·m stall torque from a 40 x 16mm motor
• Encoder version carries an AS5048A 14-bit absolute magnetic angle sensor, so the driver knows rotor position from power-up
• 11 pole pairs and a 40-turn winding give a 117rpm/V speed constant and 0.08N·m/A torque constant
• 6.34Ω phase-to-phase resistance keeps current modest — 1.1A nominal, 1.9A at stall
• Works from -20°C to 80°C, with a 120°C maximum demagnetisation temperature

Pick the encoder version for robotics or any closed-loop FOC driver that needs shaft-angle feedback; the bare motor suits standard brushless gimbal controllers that stabilise from an IMU alone.
